Leftover materials in space, such as defunct satellites or fragments from collisions, pose a threat to people on the ground because they can re-enter the Earth's atmosphere unpredictably and potentially cause damage or injury upon impact. There is a risk that these objects could land in populated areas, posing a danger to human life and property. Efforts are made to track and monitor space debris to mitigate this risk.
Materials used in space include lightweight metals such as aluminum and titanium, composite materials like carbon fiber, and specialized heat-resistant materials like ablative coatings and ceramic tiles for thermal protection. These materials are chosen for their strength, durability, and ability to withstand the harsh conditions of space, such as extreme temperatures and radiation.
It is much closer to the ground.
The main function of the International Space Station is to conduct scientific research in a microgravity environment. It serves as a laboratory for research in fields such as biology, physics, astronomy, and materials science, as well as a platform for international cooperation in space exploration. Additionally, it serves as a testing ground for technologies needed for long-duration space missions, such as those to Mars.
The observation deck is 520 feet above the ground level.
Rocks in space are formed through processes such as melting, crystallization, and solidification of materials in the early solar system. These materials can come from the remnants of supernovae explosions or from the accretion of smaller particles in space. Over time, these processes lead to the formation of asteroids, comets, and planets, which are composed of rock-like materials.

Space Patrol - 1950 Threat to Terra 3-11 was released on: USA: 14 March 1953
Meteorites are an excellent way for people to gain access to materials from space without having to go to space. They are important for unique research opportunities.
In battle, you always go for the highest ground. Space is the highest ground you can get.
Astronauts communicate with people on the ground through radio waves, which do not require a medium to travel through space. This is an example of the conversion of sound energy into electromagnetic energy for transmission. On the ground, the electromagnetic waves are converted back into sound waves that we can hear.
collect information from space
"Space Junk" gets into space because of us leaving materials behind when we visit space.
Most people in Hong Kong live in small apartments in tower blocks or skyscrapers, to make the most of the limited space on the ground.
A materials scientist with expertise in materials engineering would be knowledgeable about the properties of materials that can withstand extreme temperatures and conditions in outer space. They would study the behavior of materials under different environments and develop materials that are suitable for space applications.
